LOVELL A. RICHARDS, OF GRAYSON, CALIFORNIA.

DlSK-HARROW.

SPECIFICATION forming part of Letters Patent No. 348,693, datedSeptember 7, 1886.

Application filed May 12, 1886. Serial No. 201,996. (No model.)

To all whom it may concern:

Be it known that I, LovELL A. RICHARDS, of Grayson, county ofStanislaus, Stateof California, have invented an Improvement inDisk-Harrows; and I hereby declare the fol lowingto be a full, clear,and exact description of the same.

Myinvention relates to that class of harrows or Cultivators which areprovided with oppositely-inclined disk-gangs, the inner ends of whichhave abutting bumpers; and my invention consists in the pivot-connectionof the tongue with the beams of the gangs, whereby one gang is held tothe tongue and the other is allowed to have a lateral movement.

It consists, further, in the side braces, by which the disk-gangs areheld and their inclination varied, and in said braces in connection withthe tongue and the beams of the disk-gangs, all of which I shallhereinafter fully describe.

The object of my invention is, while providing for the variousadjustments of the diskgangs, to hold them at the same time in the samevertical plane at their meeting ends, so that said ends cannot get outof lineby moving up or down.

Referring to the accompanying drawings, Figure 1 is a perspective viewof my disk. Fig. 2 is ahorizontal section through the diskgang. Fig. 3is a detail view showing the pivot-connection of the beams with thetongue.

A is the tongue, having at its rear end the forked clip a.

Bis the beam of one of the disk-gangs. This carries the necessaryboxes,in which is mounted the shaft 1), upon which are secured the disksb.

O is the beam of the other disk-gang, carrying the shaft 0, upon whichare secured the disks 0. The inner ends of the shafts are provided withbumpers I), which abut, as shown.

Upon the inner end of the beam B is rigidly fixed a plate or tongue, E,which fits between the forked clip a of the tongue A and holds said beamagainst lateral movement.

Upon the inner end of the beam 0 are staples or guide-sockets F, inwhich is fitted loosely a bar, G, the projecting end of which has,aneye, g, which is fitted between the forked clip a of the tongue A. A pinor bolt,

II, passes down through the forked clip aand the intervening plate E ofthe beam B and the eye 9 of the bar G of the beam C, so that the tongueand beams are all pivoted together, the beam B, as before stated, havingno movement to or from thetongue, although the beam G, by reason of thestaples F and bar G, is adapted to have a sliding lateral movement onsaid bar.

I are bars or braces, the forward ends of which are connected with thesides of the tongue A by means of a hook and staple, 2 and their rearends have a series of holes, 2'', whereby they may be ad just-ablyconnected with the beams 13 C. These bars or braces hold the disk-gangsto their proper inclination, and by adjusting them at their rear endsthe angle of their inclination may be varied. At the same time thehinge-connection with the tongue in front does not interfere with thelat eral adjustment of the beam 0.

It will be observed that by reason of the connection of the beams withthe tongue the said beams are securely held with the inner ends of thedisk-gang shafts in the same plane, so that the bumper of one of theshafts cannot rise above nor overlap that of the other.

The outer ends of the two gangs may have a slight vertical play to adaptsaid gangs to the undulating condition of the ground, and provision ismade for the necessary side movement caused by a side thrust through thelateral movement of the beam 0 on the bar G, which said movement is inno wise interfered with by the side brace, I.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a disk-harrow, the combination of oppositely-arranged disk-gangshaving their inner ends abutting, one of said gangs being connected withthe frame by a fixed pivot and the other having a sliding or extensiblepivotconnection with the frame, substantially as described.

2. In a disk-harrow, the tongue A, in combination with a disk-gangconnected with its rear end by a fixed pivot, and an opposing disk-ganghaving a sliding or extensiblepivotconnection with the rear end of thetongue, substantially as described.

ICO

3. In a disk-barrow, the tongue A, in combination with the beam B,having the shaft I) and the disks 1) thereon, said beam being connectedwith the rear end of the tongue by a fixed vertical pivot, and the beam0, having the shaft 0 and disks 0 thereon, said beam having asliding orextensible pivot-connection with the rear end of the tongue,substantially as described.

4. In a disk-harrow, the tongue A, having a forked clip, a, on its rearend, in combination with the beam B of one disk-gang, said beam having aplate or tongue, E, on its inner end, fitted in the forked clip of thetongue A, the beam 0 of the other disk-gang having the sockets F on itsinner end, the bar G, fitted loosely in said sockets, and having an eye,9, on its inner end fitted in the forked clip of the tongue A, and thevertical pin or bolt H, pivoting the plate E and the bar G in saidforked clip, substantially as described.

5. In a disk-harrow, the tongue A, having the forked clip a on its rearend, in combina tion with the beam 13, having the tongue or plate E onits inner end fitted in the forked clip of the tongue A, the shaft b,suspended under the beam, and the disks 1) on the shaft, the beam 0,having the sockets F on its inner clip of the tongue A, the vertical pinor bolt H, pivoting the plate E and the bar G in the forked clip a, andthe abutting bumpers D on the inner ends of the disk-shafts,substantially as described.

6. In a disk-harrow, the tongue A, having a forked clip, a, on its rearend, in combination with the beam 13 of one of the disk-gangs, said beamhaving a plate or tongue, E, on its inner end fitted in the forked clipa, the beam 0 of the other disk-gang having the sockets F on its innerend, the bar G, loosely fitted in the sockets and having an eye, 9,fitted in the forked clip a, the vertical pin or bolt H, pivoting thebar G and the plate E in the clip, and the brace-bars I, hinged at theirforward ends to the tongue A, and adj ustably secured at their rear endsto the beams, substantially as and for the purpose described.

In witness whereof I have hereunto set my hand.

LOVELL A. RICHARDS. \Vitnesses:
